In an accompanying editorial, Jay H. Lubin, Ph.D., of the National Cancer Institute in Bethesda, Md., and colleagues note that there are many health-related consequences associated with arsenic exposure and that millions of people in both developed and developing countries rely on water with arsenic levels that exceed the recommended limit of 10 g/L.
With large numbers of people potentially exposed to arsenic in drinking water above 10 g/L, the full scope of the public health consequences of arsenic in drinking water is not yet clear, the authors write.
